TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 656,785, dated August28, 1900.

Application inea nach 9,1899. sentano. 708.418. (Numan.)

To all whom it may corr/cern:

Be it known that we, WILLIAM R. FOX, GLENN J. BARRETT, and ALBERT D.RAY, citizens of the United States, residing at Grand Rapids, Michigan,have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification.

This invention relates to type-writing machines; and the objects thereofare to improve the general construction and arrangement of the same, tocheapen the cost of manufacture thereof, and to simplify it and increaseits effectiveness. p

To this end .the invention includes a typehanger having its bearingswide apart, but the bearings of each hanger only the minimum distanceout of alinement with the bearings of its adjacent hanger.

It also includes the means for adjusting the degree of tension exertedon each key-lever and the construction of the links connecting saidlevers to the type-bars.

It also includes the detail of construction, as will be hereinafterdescribed, and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which-Figure l is a sectional view of a type-writer, showing only the parts ofthe same necessary to illustrate the invention. Figs. 2, 3, and 4 aredetail views. Figs. 5 `and 6 are details of the type-hanger. Fig. 7 is adetail of a modication of the same. Figs. 8 and 8a are views of theconnection between the type-lever and the link.

As is well known, it is desirable to have the bearings of the severaltype-lever hangers as nearlyin horizontal alinement with each other aspossible and to use as many hangers as can be placed in position tosecure the maximum number .of type-levers and to leave the hangers withtheir bearings as far apart as possible to provide wide bearings for thetype-lever pivots. In the present case this object is obtained byconstructing each hanger of a sheetmetal plate l, having a slot therein,which when the plate is doubled back upon itself centrally of said slotforms a yoke, the doubled-over ends of the prongs of which are bored outto provide sockets or bearings 3 for the type-bar cones. Theintermediate portion of the bent-over part 2 receives a screw 4, whichis threaded into the main portion of .the hanger, so said part 2 may beadjusted to vary the size of the socket 3. The end. of each hangeropposite the yoke is forked at 5 for the passage of the bolts whichsecure the same in place. l

As shownin Fig. 6, hardened bushings 6 are threaded in the sockets 3,which receive the cones of the type-bar pivots, and after the properadjustment of said bushings they are securely clamped by tightening thescrew 4. Inl the modiiication shown in Fig. 7 the ends of the pivot-pinfind bearings directly in the sockets 3, and the proper adjustment issecured through the screw 4.

To place the requisite number of hangers, it is necessary that'theyshould overlap, as shown, which necessitates the bearings of the hangersbeing in staggered relation or each alternate hanger out of alinemcntwith the hanger arranged next thereto. This, as before stated, isobjectionable, and in the present invention by making the hanger of theminimum thinness the bearings will be only the minimum distance out ofalinement and every one of the hangers maybe arranged with the samesideuppermost, so that the adjusting-screw 4 is readily accessible. Thehangers may be held in place by a ring 5', which is retained by bolts 8,which pass through the same and through the forks 5 of the hangers. Asthe hangers overlap alternately, this necessitates a space-block beingused in securingveach hanger. In holding the lowermost hangers theblocks are interposed between the same and the ring 5' and in holdin gthe raised hangers between the under side of the same and the frame` Todispense with the use of one-half of these blocks, the hangers may beheld in pairs, as shown in Figs. 2 and 3, in which a clip 3a is used,having an angular bend centrally thereof to provide two binding portions324 3X. The part 32 clamps the underlying hanger directly to the frame,no space-block being used,while the upper hanger is held by the part 3X,a space-block being interposed between said IOC a i v 656,785

hangers and the frame. The end of each link engaging the type-levers isbent at right angles and extended through the opening in the end of thelever, where it is retained by means of the split ring a', seated in therecess a2 in said end.

We claim- 1. In combinatioma type-lever hanger coinprising a platehaving one end thereof turned back upon the face of said plate and thebearings for the lever located at the turnedover portion of the plate,substantially as described.

2. In combination,a type-leverhangercomprising a doubled plate havingthe sockets for the typelever bearing located at the turned-over portionof the plate, and means for drawing the doubled-over portion of theplate toward the main portion thereof to adjust the socket,substantially as described.

3. In combination, a type-bar hanger comprising a doubled-over platehaving sockets bored at the turned-over portion of the plate to providebearings and an adjusting-screw for adjusting said turned-overportion toopen or contract the socket.

4. In combination, a type-bar hanger coinprising a doubled-over platehaving sockets bored at the turned-over portion of the plate to providebearings, and an adjusting-screw extending transversely through theturnedover portion of the plate centrally thereof threaded in the mainportion ofthe plate,snb stantially as described.

5. A type-bar hanger comprising a slotted plate doubled intermediatelyof said slot to provide a yoke having bearings formed in each prong ofthe yoke at the turned-over portion and means for adjusting saidsockets.

6. The combination with a type-writer having the type-levers arranged inbasket form, of hangers for said levers comprising fiat plates, aretaining-plate, bolts for clamping the plate, said hanger-plates havingtheir main portions forked to straddle said bolts and the forwardportion of yoke shape and doubled over with sockets or bearings formedby the bent-over end of each prong of the y'oke, said lever restingbetween said prongs of the yoke, the yoked end of each alternate hangeroverlapping the adjacent hanger.

7. The combination with a type-writing machine having the type-leversarranged in basket form,a retaining-plate, bolts for clamping said plateand hangers comprising flat plates having their rear ends slotted tostraddle said bolts and their forward portions doubled over and forminga yoke, said lever being placed between the prongs of the yoke and thepivot-pins thereof finding bearings in the doubled ends of the prongs,each alternate hanger overlapping the adjacent hanger and space-blockslocated between each alternate hanger and the frame.

8. A type-barhanger comprising a plate having a slot confined within theedges of the plate, the plate being doubled over centrally of theslotted portion whereby a yoke is provided and bearings in each end ofthe yoke.

9. In combination, a type-bar hanger comprising a flat plate having aslot therein, a yoke formed in the plate, bearings in the end of saidyoke, the yoke being formedby doubling the plate centrally of theslotted portion in a plane parallel with the axis of said bearings,substantially as described.
